The invention discloses a traffic light intelligent control system based on a PLC. The traffic light intelligent control system comprises a pedestrian flow detection module, a traffic flow detection module, a sensor module and a PLC control module. The pedestrian flow detection module is used for acquiring real-time pedestrian flow of a traffic light road section; the traffic flow detection module is used for acquiring real-time traffic flow of a traffic light section; the sensor module is used for detecting real-time light change conditions and sound signals of traffic light sections; and the PLC control module is used for intelligently controlling the conversion of the traffic lights based on the pedestrian flow, the traffic flow, the light change conditions and the sound signals. Through multiple analysis of traffic light road sections, the PLC control module is used for intelligently controlling the lighting condition of traffic lights, the traffic pressure and the blocking condition are relieved, and emergency passing of special vehicles can be achieved.

    本发明公开了一种基于PLC的红绿灯智能控制系统,包括:人流量检测模块、车流量检测模块、传感器模块以及PLC控制模块;人流量检测模块,用于获取红绿灯路段实时人流量;车流量检测模块,用于获取红绿灯路段实时车流量;传感器模块,用于检测红绿灯路段实时光线变化情况以及声音信号;PLC控制模块,用于基于人流量、车流量、光线变化情况以及声音信号,智能控制红绿灯的转换。通过对红绿灯路段的多重分析,利用PLC控制模块智能控制红绿灯的亮灯情况,缓解交通压力以及堵塞情况并可以实现特殊车辆的紧急通行。
